ApplicationJune 24, 1952, Serial No. 295,148 1 Claim. c1. 304-27 ,This inventionrelates to improvements in window scaffolds, and more particularly to animproved window scaffold of the type adapted to be supported outside ofa window for use in window washing, painting, or the like.

The main object of the invention is to provide a novel and improvedwindow scaffold which is simple in construction, which is easy to set upfor use, and which provides a safe support outside a window for a personengaged in repairing or washing the window or painting the woodworkadjacent to the window.

A further object of the invention is to provide an improved foldablewindow scaffold which involves inexpensive components, which is sturdyin construction, and which may be readily and easily set up for use.

Further objects and advantages of the invention will become apparentfrom the following description and claim, and from the accompanyingdrawings, wherein:

Figure 1 is an outside view of a portion of a building adjacent awindow, showing an improved window scaffold according to the presentinvention set up for use.

Figure 2 is a vertical cross sectional view taken on the line 2-2 ofFigure 1.

Figure 3 is a horizontal cross sectional view taken on the line 33 ofFigure 1.

Figure 4 is a perspective view showing the various components of thewindow scaffold assembly in separated positions.

Referring to the drawings, the scaffold assembly comprises an anchoringframe, shown generally at 11 which comprises a pair of vertical barmembers 12, 12 and a horizontal cross bar 13 rigidly secured to thevertical bar members 12, 12, by means of respective flanged brackets 14,14 and fastening bolts 15, 15. As shown in Figure 3, the brackets 14 areprovided with respective pairs of flanges adapted to embrace thehorizontal bar 13 and the adjacent vertical bar member 12 so as toprevent relative rotation between the horizontal bar 13 and the verticalbar members, and the bolt 15 passes through the horizontal bar member,the Web portion of the brackets 14 and the vertical post to lock thevertical posts 12 and horizontal bar 13 together. The vertical barmembers 12, 12 are adapted to be supported on the floor at the inside ofa window, as shown in Figure 2, and the horizontal bar 13 is greater inlength than the width of the window, whereby it serves to prevent theframe 11 from being pulled through the window. Secured on the horizontalbar 13 inwardly spaced from the respective vertical bar members 12, 12are the respective collar brackets 16, 16 having secured thereto therespective chain links 17, 17 to which are connected the respectiveturnbuckle members 18, 18.

Designated at 19 is a rectangular platform, and positioned transverselyof the platform adjacent to and spaced from each end of the latter is anupstanding right triangular frame member 20, the frame member having thebase leg 20' connected to the platform for movement from the upstandingposition to a horizontal ice position. Each frame member 20 alsoincludes a short leg 20" and a hypotenuse leg 20". Connected to the endsof the turnbuckle members 18, 18, are the respective conventional springhooks 22, 22 which are engageable with the connection point of the shortleg 20" with the hypotenuse leg 20" as indicated by the numeral 21 ofthe frames 20 in the manner shown in Figure 2, whereby the platform 19may be supported in a substantially horizontal position, adjusted bymeans of the adjustable turnbuckles 18, 18, the rear edge of theplatform 19 being in abutment with the wall below the window, as shownin Figure 2. It is to be noted that the assembly consisting of chainlink 17, the turnbuckle 18, and spring hook 22 constitutes a flexiblehanger member.

Secured to the forward marginal portion of the platform 19 are thespaced inverted U-shaped brackets 24 arranged to receive the forwardtransversely extending stud elements 25 of the respective upstandingguard frames 26, 26. As shown in Figure 4, each guard frame 26 comprisesthe vertical leg 27, the downwardly and rearwardly inclined leg 2Sintegrally connected with the vertical leg 27, and the inwardly inclinedbrace leg 28 which extends downwardly and inwardly from the intermediateportion of the vertical leg 27 and is provideo at its end with atransversely extending stud element 25. The lower ends of the inclinedlegs 28 are likewise provided with transversely extending stud elements29 which extend in the same direction as the stud elements 25 and whichare engageable in inverted U-shaped bracket elements 30 secured to therear corner portions of the platform 19. It- Will be readily apparentthat the guard frames 26 may be engaged in the bracket members 24 and 30by inserting the stud elements 25 and 29 in said bracket members andmoving the guard frames forwardly to the positions thereof shown inFigure 4.

Designated at 32 is a rail member formed at its bottom edge with therespective notches 33, 33 adapted to lockingly engage with respectiveoffset bracket members 34, 34 secured to the top portions of thevertical legs 27, 27. With the bar 32 engaged with the offset brackets34, 34 a substantially complete enclosure is provided around the sideand forward marginal portions of the platform 19, and this enclosure isrigidified by the combined effects of the horizontal top bar 32 and theinclined strut elements 28, 28.

The platform 19 is provided at the intermediate portion of its forwardmargin with a handle 35 to facilitate transportation of the platformwhen the scaffold is being erected or being transported from place toplace.

In setting up the scaffold, it is merely necessary to place theanchoring frame 11 inwardly adjacent the window and to engage the springhooks 22 with the top portions 21 of the frame members 20 with theplatform 19 disposed outside the window, as shown in Figure 2. Theplatform 19 may be adjusted to its desired position by adjusting theturnbuckles 18. The platform 19 will thus be supported with its rearedge in abutment with the wall below the window. The guard frames 26 maythen be mounted on the platform in the manner shown in Figure 4 with thetransversely extending stud elements 25 and 29 engaged in the respectivebracket members 24 and 30. The top bar 32 may then be engaged with theoffset bracket members 34, said bracket members being lockingly receivedin the notches 33 to complete the assembly. The scaffold is then readyfor use for any desired purpose, such as window washing, glazing,puttying, or painting, Without requiring the use of a ladder or a windowbelt.

While a specific embodiment of an improved window scaffold has beendisclosed in the foregoing description,

3 it will be understood that various modifications within the spirit ofthe invention may occur to those skilled in the art. Therefore, it isintended that no limitations be placed on the invention except asdefined by the scope of the appended claim.

What is claimed is:

In a scaffold, a platform, a pair of right triangular guard frameshaving base sides secured to the platform, said guard frames having apexportions, brackets on said guard frames near said apex portions of theguard frames, and a guard rail extending between the guard frames andremovably and securably engaging the brackets, said guard framesextending crosswise of the platform, hinge means securing the guardframe to the platform, and braces on the guard frames engageable withthe platform for holding the guard frames against pivoting inwardlybeyond erect positions, the engagement of the guard rail with thebrackets serving to preclude outward pivoting of the guard frames out oferect position.
